HEY GUYS,,Found this article by David Vizard in my new Grassroots Motorsports issue,, A real lie detector for comparisons..
It should work on our Turbo cars with the right heat resistant material..
Just thought I would share..

 

Late to the party brother... I can lend you my test rig, you can put on any boost gauge that you can hook to a -3AN. You just remove your rear o2 and screw the rig in. if you want pre turbo I have a fitting for that but you need to drill and tap. If you want pre cat you will need to add a second o2 bung.
